Step 1: Select Wiring Harness Gauge
-
14 Gauge (Included) - Our standard wire gauge
-
12 Gauge (+$20.00) - Upgrade your wires that goes to the harnesses plugs and factory harness to thicker wire.
Step 2: Select Power Wire Gauge
-
14 Gauge (Included) - Our standard wire gauge. Supplied with 20 AMP Fuses.
-
12 Gauge (+$8.00) - Upgrade your power wire that goes to the harnesses relays and your vehicle's battery to thicker wire. Supplied with 30 AMP Fuses.
Step 3: Soldered Connections
- No (Included)
-
Yes (+$7.00) - Have us solder your machine crimped connections so you can have the most secure & reliable harness. Solder is NOT common in vehicles, but is routine in aircraft because it produces the best union of wire to terminal.
Step 4: Select Batteries Equipped
- One Battery
- Two Batteries
Step 5: Daytime Running Lights
-
No - Dodge Rams manufactured in the USA were not equipped with Daytime Running Lights.
-
Yes (+$30.00) - Includes Daytime Running Light Circuitry. For vehicles that were manufactured in Canada equipped with Daytime Running Lights.
Unsure whether or not your vehicle has daytime running lights? If your Dodge Ram is equipped with Daytime Running Lights your Daytime Running Lights will illuminate high beam at low intensity.
Additional Information: Connector Type
-
High Temperature Connectors with Moisture Seals (Included) - Maximum Temperature = 572º F / 300º C - Most harnesses are manufactured with plastic connectors that cannot withstand high temperature and will melt. Ours are premium connectors designed for high temperature and prevents melting.
All connections are machine crimped and shrink wrapped to the highest industrial standards.
Why use a Heavy Duty Relay and Headlight Wiring Harness Upgrade?
Reason #1: To minimize the VOLTAGE DROP in factory headlight systems. Voltage drop lowers the energy delivered to your headlight filaments which reduces their output. Voltage drop is a result of electrical power being run for long distances through thin wires. You can visualize voltage drop by imagining yourself drinking a beverage through a long thin straw (electric energy is the "beverage" and the wire is the "straw").
Reason #2: Using a 9004 (HB1) to 9007 (HB5) Heavy Duty Relay and Wiring Harness Upgrade reduces the current that is handled by the head light switch by a large margin. This reduction in current greatly increases the life of your head light switch.
For example: Your factory headlight systems POWER flows from BATTERY to HEAD LIGHT SWITCH in passenger compartment. When head light switch is turned on, POWER flows back out into engine compartment and then illuminates HEAD LIGHTS. Notice the long distance that power must travel. To make matters worse, typical factory headlight wires are 18 Gauge or LESS. These long runs of thin wires starve your head lights of energy.
ADDING A 9004 (HB1) to 9007 (HB5) HEADLIGHT WIRING HARNESS & RELAY UPGRADE:
Increases the power delivered to your head lights by minimizing the distance power must flow from battery to head lights AND by passing this power through thick, 14 Gauge or 12 Gauge USA made wire (Smaller Gauge = THICKER wire) with the highest quality copper conductor.
AFTER INSTALLING A 9004 (HB1) to 9007 (HB5) HEADLIGHT WIRING HARNESS & RELAY UPGRADE:
POWER flows from BATTERY to HEAD LIGHT SWITCH in passenger compartment. When head light switch is turned on, POWER flows back out into engine compartment and then ACTIVATES RELAYS on the wiring harness. The RELAYS then CONNECT the HEAD LIGHTS DIRECTLY to BATTERY through 14 Gauge or 12 Gauge wires.
In simplified terms, the 9004 (HB1) to 9007 (HB5) Heavy Duty Relay & Headlight Wiring Harness Upgrade is triggered by the head light switch and when triggered, the harness supplies power to the head lights through a more efficient path.
This relay and wiring harness upgrade is one of the most simple and effective ways to improve dim headlights and overall headlight performance by increasing both your low beam and high beam illumination. Perfect for dark roads, off-road, and rural areas!
